Cut-off Wheel KLINGSPOR FLEX 27 125×6.0×22.2 A46N SUPRA ALU 2226

The KLINGSPOR FLEX 27 125×6.0×22.2 A46N SUPRA ALU (model 2226) cut-off wheel is a 125 mm abrasive disc developed for cutting and light grinding of aluminium and other non-ferrous metals. With a 6.0 mm thickness and a 22.2 mm bore, this wheel is intended for use with standard angle grinders. The A46N SUPRA ALU abrasive grain is formulated to deliver steady material removal on softer metals while maintaining wheel life and dimensional stability under typical metalworking conditions.

Advantages

The wheel combines an abrasive composition optimized for aluminium with a balanced bond system to provide predictable cutting speed and reduced glazing. Its 6.0 mm thickness offers a compromise between cutting robustness and control, while the 125 mm diameter keeps the tool compact and suitable for precise operations. The 22.2 mm central bore matches common grinder flanges for straightforward mounting.

Suitable for

• Cutting aluminium profiles, sheets and extrusions
• Trimming and separating non-ferrous metal parts
• Fabrication tasks in metalworking workshops and maintenance
• On-site repairs and installations where compact angle grinders are used

Key specifications

• Diameter: 125 mm
• Thickness: 6.0 mm
• Arbor bore: 22.2 mm
• Abrasive grit and type: A46N SUPRA ALU
• Intended materials: aluminium and non-ferrous metals

How to use

Fit the wheel onto a compatible angle grinder with a 22.2 mm spindle and secure it according to the grinder manufacturer’s instructions. Use appropriate speed settings within the wheel’s rated rpm and apply steady, even pressure while cutting; avoid excessive side force that could stress the disc. Keep a consistent feed rate to reduce clogging and heat build-up when working with aluminium. Replace the wheel when wear or damage compromises cutting performance.

Usage recommendations

Always use appropriate personal protective equipment including eye protection, gloves and hearing protection. Use a guard and follow safe operating practices for angle grinders. For best results on aluminium, clean work surfaces of grease and contamination, and avoid prolonged dwell to prevent material adhesion to the abrasive.
